I also noticed that rather than the 'date' showing up where it is supposed to, the date has an episode number - like E88.
Unless you have a Series 3 or earlier, you can control whether date or episode number gets displayed in the folder and how it is sorted by using the B
The only time I've seen what you are describing is when I had suggestions turned on, and an episode got recorded as a suggestion (not as a result of the One Pass) and then immediately got deleted because there was no room for suggestions. It would be in the folder because it had the common series ID but the One Pass rules for retention wouldn't apply. It had to happen a couple of times before I figured out what was going on. This days I don't record suggestions and I keep a good percentage of free space so that I can recover deleted recordings.
Of course, if you had "Keep Until I Delete" set for your One Pass, it wouldn't even record new shows until you manually delete one of the five old ones; I'm sure you haven't done this.
Otherwise I've always seen retention operate First In, Last Out based on order of recording. I don't see how even bad guide data could mess that up, because the guide data doesn't have anything to do with the order in which something was recorded.
